Most business owners discover this the same way. They open ChatGPT, type the question a customer would ask — best orthodontist in Guadalajara, reliable commercial roofer near Leeds — and read a confident, well-organised answer that recommends three competitors and never mentions them.
The instinct is that something has gone wrong, or that a competitor has paid for placement. Neither is usually true. The mechanism is duller than that, and once you see it, the fix stops being mysterious.
Assistants don't look you up. They recall you.
A search engine maintains an index of pages and ranks them against a query. An assistant does something different: it produces the most plausible continuation of the text so far, shaped by everything it absorbed during training and, when search is enabled, by a handful of pages fetched at that moment.
Neither path involves a list of every business in your category. So the question an assistant is really answering is not who is the best roofer in Leeds? It is closer to when text on the web discusses roofers in Leeds, which names appear, and in what terms?
If your business rarely appears in that kind of text, you are not ranked low. You are absent from the material the answer is assembled from.
Three reasons a real, successful business goes missing
Your description isn't consistent. The model needs to connect a name to a category and a place. If your site says "design studio", your directory listing says "marketing agency", and your LinkedIn says "brand consultancy", each mention reinforces a different association, and none of them accumulates enough weight to surface.
Your best material isn't quotable. An assistant needs a sentence it can lift. "We've served the region for 20 years with an unwavering commitment to quality" is not that sentence — it contains no fact and it fits every competitor equally. "We install standing-seam metal roofs on commercial buildings in West Yorkshire, typically 4–6 week lead time" is. The second one can be recalled, matched to a question, and reproduced. The first can only be skimmed past.
You're absent from the sources that get cited. Assistants lean heavily on pages that aggregate and compare — industry directories, trade association listings, local roundups, review platforms, forum threads where someone asked your exact question two years ago. When an assistant cites its work, these are disproportionately what it cites. A polished site with no presence in that layer is a well-built room with no door.
Why "we rank #1 on Google" doesn't settle it
Ranking and being recommended reward different things.
Search ranking is competitive and positional: your page is measured against other pages for one query, and the prize is a click. An assistant isn't allocating clicks. It's composing a paragraph, and it needs claims that are short, specific, and safe to repeat. A page can rank first and still offer nothing liftable, and a modest page on a directory nobody visits directly can end up quoted in thousands of answers because its format is exactly what an assistant needs.
This is also why the two can diverge sharply. We regularly see businesses that dominate their local search results and appear in none of the four major assistants' answers.
What to actually check
Before changing anything, find out where you stand — and be specific about it:
- Ask the real questions. Not "tell me about my company", which prompts the assistant to work from your name and flatters you. Ask what a customer with a problem and no knowledge of you would ask.
- Ask every assistant. ChatGPT, Claude, Gemini, and Perplexity draw on different training data and different search back-ends. Being absent from one tells you very little; being absent from all four is a pattern.
- Read the citations, not just the answer. Where an assistant shows its sources, that list tells you which pages it trusts in your category. Those are the pages worth appearing on.
- Repeat it. A single response is a sample, not a measurement. Answers vary between runs, and a name that shows up one time in five is a different situation from one that never shows up at all.
The uncomfortable part is that the finding is often that you're not mentioned anywhere, by anything. That is not a reason to avoid looking. Every month spent not knowing is a month your competitors accumulate the mentions that make them the default answer, and that advantage compounds quietly: each citation makes the next one likelier.
